Answer: It sounds as if your physician performed an esophageal motility study. You’ll typically report this procedure with 91010 (Esophageal motility (manometric study of the esophagus and/or gastroesophageal junction) study with interpretation and report).

Sometimes, your gastroenterologist might opt for the use of a medication stimulant during the motility studies. In such a scenario, you report the additional procedure with +91013 (Esophageal motility (manometric study of the esophagus and/ or gastroesophageal junction) study with interpretation and report; with stimulation or perfusion (e.g., stimulant, acid or alkali perfusion) (List separately in addition to code for primary procedure)).
